Water Display With LED'S - Beginner Needing Help!!

Hi Everybody,

I'm a Product Design student working on a Physical Computing Module where I'm hoping to create a Water Fountain display which acts with music. I'm aiming at five water jets which I want to program differently for each so they each react and come on to a different frequency. When they come on I want them to be accompanied by an illuminated LED.

I'm very new to Arduino and electronics in general (my second project ever) and I'm unsure really how to go about creating it. I've purchased...

Components Got

Sound Detector https://www.coolcomponents.co.uk/sound-detector.html

5 x http://cpc.farnell.com/adafruit-industries/997/solenoid-valve-plastic-water-12v/dp/SW04771

I presume I require a pump as well and was aiming at purchasing this or similar to then split the water to five jet via the Solenoids


Have I gone about this right?

Any help I would be very grateful or any directions to existing projects which will help me get underway

Kind Regards

Will that pump generate the flow rate you need? Research what sort of flow rate you need. I didn't view the link, but perstalitic pumps aren't usually good for high flow.

(Also - you only need the pump if you care about wasting water ;-) )

You'll need MOSFETs to drive the solonoids, and a power supply for them. And flyback diodes to clamp the back EMF.

You'll need a way to split the sound up into different frequency bands, if you're going to make your fountain act like a very wet graphic equalizer. I didn't read the link (of course), but the MSEQ7 may be a useful part - it's the classic go-to part for making graphic equalizers (don't try to pick apart the sound into frequency bands on the Arudino)

You may need some valves for each fountain output for balancing and adjustment.

You need nozzles for each output of the fountain.

If you intend to have more than one jet operating at a time, you will need 5 pumps or will need a pressure regulator. If just one pump and jet working, then turn on a second jet, the first jet will have less pressure. Turn on a third jet and still less pressure for all three, etc.
